[ French version / Version française ]

The Learn Pack is a demo pack focused on all basic functionalities. Demos are simple, coded in Lua, well commented, and all based on OpenGL 2.1 in order to run on most of platforms (Windows, Linux, macOS and Raspberry Pi with OpenGL 2.1 support).

The Learn Pack can be downloaded from the following link:

1 - Demos learn/01-basic/

01-clear-screen The simplest GeeXLab demo: how to clear the screen with an uniform color. - source code @ GitHub

02-hello-world The first demo showing text-based animation. This demo is highly recommended. - source code @ GitHub

03-line This demo shows how to draw lines. - source code @ GitHub

04-tiangle The Hello World of graphics programming: the RGB triangle. With this demo, you will have all the knowledge to build Unreal-Engine-4-like rendering ;) - source code @ GitHub

05-bouncing-quad-screen-borders A demo that shows how to set the position of an object. And how to code time-based animation.

06-reference-grid Your first 3D demo. You will learn how to create a 3D camera and how to use a reference grid.

07-texture-mapping This demo shows to render an image on an object: it's texture mapping.

08-textured-box The first serious 3D demo: a textured cube!

09-wireframe-object This demo shows how to render an object in wireframe.

10-text-ttf-font This demo shows how to use TTF fonts (True Type Font) to render texts.

11-loading-3d-model This demo shows how to load a 3D model from a file (*.3ds, *.obj, etc.)

12-live-coding-from-file This demo shows how to set up the FRAME script to do live-coding. Live-coding is the ability to update the demo source code and to get an immediat feedback in GeeXLab.

2 - Demos learn/02-intermediate/

01-phong-lightinga This demo shows how to use a lighting GPU program (in GLSL).

02-normal-mapping This demo shows how to use a moer advanced lighting GPU program (in GLSL) to do normal mapping.

03-sphere-env-mapping This demo shows how to use an environment mapping GPU program.

04-bouncing-ball This demo shows how to use basic mechanical equations to animate the fall of a ball.

05-webcam-win32 This demo shows how to use the webcam (Windows only).

06-render-target This demo shows how to use the render targets. Render targets allow to render scene into textures and to use those textures for other effects. Every videogames use one or several render targets.

07-vertex-pool This demo shows how to display particles.

08-gear This demo shows how to display a gear mesh and how to use basic gear equations to animate gears. This demo shows how to use ImGui functions to display tool boxes as well.

09-bullet-physics This demo shows how to use the Bullet Physics engine in a very simple animation. And to make the learning simpler, the demo uses the very cool Hello! framework.
